December in Puerto Rico typically marks the start of the dry season and offers visitors and residents a respite from the hotter, more humid months. Characterized by lower humidity, sunshine, and comfortable temperatures averaging in the low 80sF (high 20sC) during the day and dipping to the low 70sF (low 20sC) at night, this period provides ideal conditions for outdoor activities. Rainfall is significantly reduced compared to the wetter months, though brief showers can still occur.
Knowing the typical climatic conditions for this specific period is valuable for a variety of purposes. Tourists planning winter getaways can confidently pack lighter clothing, anticipate beach-friendly weather, and schedule outdoor excursions. The drier weather also has implications for the agricultural sector, allowing for certain crops to be harvested and others to be planted. Historically, this period signifies the transition into a more temperate climate, impacting local festivals and cultural activities which often take place outdoors.
